Hi Carmel & All,
In 1997 the Canadian Nature Federation sponsored a Canadian Lady
Beetle Survey which included a visual guide to ID. On the internet I was
not able to locate anything comparable. Bug Guide is useful if one can
learn to avoid the misleading images.
Yes Adalia bipunctata (two spotted) was sometimes abundant.
For a painless introduction to beetles in general (mug shots)
Beetles of Eastern North America Authur V. Evans 2014 has beautiful
illustrations. Be aware that "God has an inordinate fondness for beetles".
